A 46-Year-Old Man with an Incidental Finding of a Papillary Thyroid Carcinoma in a Thyroglossal Duct Cyst.

BACKGROUND The thyroglossal duct cyst, which develops from the midline migratory tract between the foramen cecum and the anatomic location of the thyroid, is the most prevalent congenital abnormality of the neck, accounting for about 70% of all cervical neck masses in children and 7% in adults. Only up to 1% of these abnormalities contain malignant thyroid tissue, with 90% of those cases being papillary thyroid carcinoma. Thyroglossal duct cyst is rarely linked to carcinoma.

Comparative Study of Clinical Features of Patients with Different Types of Benign Paroxysmal Positional Vertigo.

: Even though BPPV is one of the most common causes of vertigo, it is often underdiagnosed and omitted in the diagnosis of patients reporting vertigo. The aim of the study was to establish a diagnostic pattern useful in patients admitted due to vertigo, based on the most common clinical characteristics of patients suffered from posterior canal BPPV (PC-BPPV), horizontal canal BPPV with geotropic (HCG-BPPV) and apogeotropic nystagmus (HCA-BPPV). : The analysis covered the results obtained in 105 patients with a positive result of the Dix-Hallpike maneuver or the supine roll test.

Evaluation of a Fatigue Detector Using Eye Closure-Associated Indicators Acquired from Truck Drivers in a Simulator Study.

This paper presents a camera-based prototype sensor for detecting fatigue and drowsiness in drivers, which are common causes of road accidents. The evaluation of the detector operation involved eight professional truck drivers, who drove the truck simulator twice-i.e.

Suppressive effect of electromagnetic field on analgesic activity of tramadol in rats.

The electromagnetic fields (EMFs) have been shown to alter animal and human behavior, such as directional orientation, learning, pain perception (nociception or analgesia) and anxiety-related behaviors. The aim of this study was to evaluate the influence of electromagnetic fields of high-frequency microwaves on pain perception and anti-nociceptive activity of tramadol (TRAM) - analgetic effective in the treatment of moderate to severe acute and chronic pain states. Electromagnetic fields exposures of a)1500 MHz frequency and b) modulated, 1800 MHz (which is identical to that generated by mobile phones) were applied.

[The application of KTP laser in otolaryngology - 3 years experience].

Introduction: The KTP laser is popularly called the green laser is a type of Nd: YAG laser zawdzięczający its name from the additional element of KTP crystal which is a wavelength of 532 nm.

Aim: The aim of this paper is to present our 3-year experience in the application of KTP laser in otolaryngology.

Material: In the Department of Otolaryngology, CSK MON Military Medical Institute in Warsaw from 2008, performed 211 operations using the green laser.
